Will an exhaust manifold off of a 2000+ 3rz (2.7l) taco fit on a 1997 3rz 4runner?

 

Yessir. Same engine, same manifold. Just make sure to check on O2 sensor location. If by chance its a Cali taco, and your 4runner is not, it may have a sensor in the manifold where as yours doesn't, or vise versa.
